# `range`

Returns a list containing an arithmetic progression of integers:

    {% for i in range(0, 3) %}
        {{ i }},
    {% endfor %}

    {# outputs 0, 1, 2, 3, #}

When step is given (as the third parameter), it specifies the increment (or decrement for negative values):

    {% for i in range(0, 6, 2) %}
        {{ i }},
    {% endfor %}

    {# outputs 0, 2, 4, 6, #}

Note

Note that if the start is greater than the end, `range` assumes a step of `-1`:

    {% for i in range(3, 0) %}
        {{ i }},
    {% endfor %}

    {# outputs 3, 2, 1, 0, #}

The Twig built-in `..` operator is just syntactic sugar for the `range` function (with a step of `1`, or `-1` if the start is greater than the end):

    {% for i in 0..3 %}
        {{ i }},
    {% endfor %}

Tip

The `range` function works as the native PHP range function.

## Arguments

- `low`: The first value of the sequence.
- `high`: The highest possible value of the sequence.
- `step`: The increment between elements of the sequence.
